EJNITED STATES PATENT. OFFICE LOUIS A. SUEKOFF, OF CHICAGO, ILLINOIS, ASSIGNOR F ONE-HALF TO FRED A. NACHMAN, OF CHICAGO, ILLINOIS SPRING-FILLED MATTRESS Application filed November 1, was. Serial no. snare.

This invention has for its object to provide a novel mattress of the springfilled type which is simple, can be produced at low cost and in which tufting of the mattress after Otherwise completing the same" is obviated, a

further object of the invention being to provide quilted top and bottom walls of such mattresses which are so constructed and ar ranged as to enable a peripheral quilted wall, (commonly termed boxing) to be stitched to the edges of said top and bottom walls by machine stitching after the mattress springs have been interposed between said topand bottom walls, to thus produce a finished mattress ata minimum cost of labor.

In the mattress making art, a very considerable portion. of the cost of the finished product is the labor, as skilled mechanics are requiredfor certain. of the operations.

My invention is directed to eliminate the necessity of employing skilled labor as the only manual operations required to be performed in the construction of the mattress of my invention may be easilyand efficiently er'formed by unskilled labor as will appear om the following specification.

In the accompanying drawings, I have illustrated themattress of my invention and the successive conditions of the materials of which'the mattress isconstructed and the successive steps involved in gradually associating said materials until the finished mattrees is produced.

Fig. 8 is a fragmentary sectional view of the completed mattress.

As the construction of the mattress of my invention will be most readily comprehended by describing first the successive steps of the method of making the same, the latter is herein fully described.

The method of manufacturing springfilled mattresses in accordance with my invention, consists in first laying u on a plain strip A of a suitable fabric sucii as burlap, cotton duck, etc., a strip B which preferably is provided with suitable lines C and D imprinted thereon in any suitable manner to extend longitudinally and lines E and F extending transversely of the lines C and D to divide the surface thereof into small square areas of equal size. In each of these areas there is provided an opening such as a slit -or slot G extending preferably diagonally of the square and of suitable length to permit insertion of the end coil of a spring theretbrough. It will be noted that the lines C and D alternate with each other and that the lines E and F alternate with each other.

The two strips or sheets A and B, which are slightly longer and wider than the --top or bottom wall of the mattress core to be composed in part therefrom, are then stitched together by certain lines of stitching which follow the imprinted lines above mentioned. For example, the initial lines of stitching will follow the lines C and E, respectively, the total number of lines C and D being odd as is also the total number of lines E and E, the outermost lines D and E being nearest adj acent the side edges and ends, respectively, of the fabric sheets A and B. Thus the lines of stitching C and E may be said to border areas, each of which comprises four of the slitted or slotted square areas each of which is bordered by lines G, D, E, and F, it being apparent, of course, that along the side and end edges of the sheetsthe initial lines of stitching which are indicated by the same reference characters C and E as would indicate the imprinted lines followed thereby, border three sides only of areas, each of which contains two of the small squares and at the 100 corners of the sheets border only two sides of single small square areas.

The stitching is effected preferably by a gang sewing-machine. The sheets A and B, after being thus stitched together by the stitchings C and E, are then inverted so that sheet A is above sheet B. Then upon sheet A is disposed a layer H of padding material such as cotton, hair, etc; and upon this layer-H there is laid a sheet of ticking J. The latter and the layer H are then stitched to the sheets A and B by lines of stitching D and F which alternate with the lines of stitching C and E to thereby complete the slitted or slotted small square pockets which were originally defined by the lines C, D, E and F, imprinted upon the sheet or strip 13 so that the said lines of stitching D and F serve two functions, viz: to complete the stitching together of the fabrics A and B and to secure the padding and ticking to the same and form what, in the upholstery art, are known as biscuits, each of which is equal in area to four of the square pockets over=the entire area of the top and bottom walls of the mattress.

The padding and ticking are preferably of length and width slightly greater than that of the sheets A and B and are stitched along their edges to thevlatter and, preferably, also to a boxing strip which forms the peripheral walls of the mattress- This stitching of the several layers to the boxing strip is, of course, elfected after springs K have been mounted between two of the padded stitched top and bottom wall structuresby inserting the end coils of said springs into opposed square pockets bordered by the several lines of stitching C, D, E, and F.

The surplus material at the side and end edges of the top and bottom wall structures maybe fashioned to form a roll edge and suitably stitched to a plain 'or added boxing strip,'it being obvious that a s illed mattress maker will treat these edge portions according to his own ideasof a neat ultimate finish.

I prefer, however, to employ for boxing, a padded strip of material. such as is shown inFigs, 5, 6, and .T, which consists of an in- 'ner layer L of fabric, an intermediate layer .M otpadding and an outer ticking N. the latter and the elements L' and M being secured together by lines [of stitching O and P, respectively, the lines of stitching 0 being spaced from and extending parallel with the longitudinal edges. of the structure so as to leave enough of the fabrics and padding along the side" edges to form, conjointly with the similar edge portions of the top and bottom wall structures, the roll edge Q shown in Fig. 8, the exactm'anner of effecting thestitching together of the fabrics B-and L and of the tickings J and N being unimportant and selective by the mattress maker.

The resulting mattress presents a structure wherein the quilted top and bottom walls a e directly associated with the means fut engag; ing the interposed springs in that the latter are completed by the lines of stitching which complete the quilting of said walls, said lines of stitching thus performing two functions and obviating the ex a stitch! ng which would otherwise be required to complete th spring engaging portions of .saidwalls.

Obviously the relation of the lines of stitching which form the biscuits of the top and bottom wall structures with rcspec number of small squares or spring-em} pool; ets may be varied. it being found in practice, however, that if the biscuits are of the same size as said small squares or pockets, the paddling will be so compressed as to produce an uncomfortably hard surface so that it is more desirable to have said biscuits each of a size or area to cover a plurality of said small squares or pockets.

I claim my invention:

4. A mattress comprising top and bottom walls having opposed face portions equipped with spring retaining means, springs interposed hetween said top and bottom walls and engaged with said spring retainin means, padding and ticking constituting tie outer portions of said top and bottom Walls and se cured to the said opposed face portions by lines of stitching extendinglongitudin ally and transversely, respectively, of said Walls, some of said respective lines of stitching extending through and iionstitutin 1 parts of said, spring retaining means, and a fimxing strip secured along its top and bottom edges to the peripheral edges of said top and bottom walls.
